4 MAINTENANCE AND BATTERY REPLACEMENT
4.1 Precautions
Although the Liebert® PSI5 is designed and manufactured to ensure personal safety, improper use can result in electrical
shock or fire. To ensure safety, observe the following precautions:
• Turn Off and unplug the UPS before cleaning it.
• Clean the UPS with a dry cloth. Do not use liquid or aerosol cleaners.
• Never block or insert any objects into the ventilation holes or other openings of the UPS.
• Do not place the UPS power cord where it might be damaged.
4.2 Battery Charging
The batteries are valve-regulated, non-spillable, lead-acid in all models except for the LI, which uses LiFePO4 type lithium-
ion batteries. In all cases, the batteries should be kept charged to retain their design life. The PSI5 charges the batteries
continuously when it is connected to input power. If the PSI5 will be stored for a long time, Vertiv™recommends connecting
the UPS to input power every 4 to 6 months for at least 2 hours for LI models and 24 hours for lead acid models to ensure
full recharge of the batteries.
4.3 Replacing the UPS Batteries
IMPORTANT! Before you proceed, please review the battery safety precautions available at
https://www.vertivco.com/ComplianceRegulatoryInfo .
You may safely replace the internal battery pack. See the Specifications on page 37, for the part number of the replacement
battery for your UPS model number.
NOTE: Replace the battery with the same type and number as originally installed.
NOTE: The internal battery pack is hot-swappable. However, caution should be exercised because during this
procedure the load is unprotected from disturbances and power outages. Do not replace the battery while the UPS is
operating in Battery Mode. This will result in a loss of output power and will drop the connected load.
To replace the batteries on 1U and 2U models:
1. Remove the front bezel by pulling firmly until the snaps release.
2. Disconnect the battery connector by squeezing the ends and gently pulling the two pieces apart.
3. Remove the two screws and the metal battery cover plate.
4. Slide out the existing battery kit and disconnect the battery terminals from the connector. Disconnect the red
wire first, then the black.
5. Plug the removed connector into the terminals of the new replacement battery kit. Plug the black wire in first,
then the red.
6. Orient the connector and the new battery in the same way as the original battery and slide into UPS.
7. Reconnect the two halves of the battery connector and slide the front panel back on until it clicks.
8. Replace the metal plate and secure with the two screws.
9. Snap the front bezel back on.
